    Re: Question regarding Interrupt handler - No DT_Ints used.

    It's probably good to be aware of the minimal context saving done automatically, but for the code in question it's not using any computed GOTO's so I think you should be safe with the code pretty...

    Re: Question regarding Interrupt handler - No DT_Ints used.

    I would be pretty cautious about that. pbp code is full of goto's

    Re: Question regarding Interrupt handler - No DT_Ints used.

    Section 6.5 (page 39) of the PIC10F322 Data Sheet declares the only context saving it does is saves the PC. Example 6-1 spells out the minimal Assembly code required to accomplish that feat (note,...

    Expanding my Horizons

    Recently I decided to learn to program in C, and learn about the 16-bit PIC processors. I bought a couple of books, the Microchip Explorer 16/32 Development Board, the PIC24FJ128GA010 mezzanine,...

    Re: Question regarding Interrupt handler - No DT_Ints used.

    Thanks for your input tumbleweed. What you said coincides with what I have been able to gather by looking at the LST file. As Richard pointed out, I may have been stepping on system variables but...

    Re: Question regarding Interrupt handler - No DT_Ints used.

    There's nothing wrong with saving all that stuff, but that's a lot of bother for what you've got going on.

    If all you do is simple sets and tests with port bits and bytes like you have then you...

    Re: HT16K33 LED Controller

    I'm not very good at this but since no one else chimed in here's my thoughts. I was looking at the data sheet and I don't see this as a settable mode. Page 61. Most people don't bother with an...

    Re: Question regarding Interrupt handler - No DT_Ints used.

    Hi,
    You could try to use only ReEnterPBP.bas to take care about saving and restoring variables.
    So just call
    SavePBP_H:
    After saving status wreg etc,
    And before you exit interrupt call ...
